When using EA, auto update the list of cluster node members similar to what happens within Atlas
As we add new nodes, it requires us to update the URI. Would like a way to have this automatically update.

Would like the ability to restore a single zone based shard
If the idea that data is stored within a region (via zone based sharding) and they are "just" replica sets, why can't we just restore a single shard? Right now we have to restore the entire cluster.

Create and use db links in Mongodb
Allow Mongodb to access an external database for:
1.select identifiers on an external rdbms (ex: postgres, sqls, oracle, ...)
2.use these identifiers to perform aggregations in MongodbCurrently, it is necessary to use a third-party tool that connects to several data sources to perform these actions.
The idea is to be able to perform these "joins" only in Mongodb CLI.Regards,

Add build for Linux Alpine and Debian
A build in ARM support (Apple M1) for Alpine Linux (or Debian) is needed to run the mongocryptd process. Currently the official node docker images are available only in Alpine and Debian.

Support split documents on disk
As an application's functionality grows, if kept unchecked it is easy for average document sizes to grow simultaneously.
Large documents can have a significant impact on the performance of MongoDB. However, often the application doesn't actually need the entire document to service a request. Likewise, often queries are sent to MongoDB with a projection, excluding substantial (in terms of byte size) parts of the document.
MongoDB has no ability to optimise these projections (except for covered queries which are not always practical).
MongoDB should provide the ability to specify a "split" in a document such that the query planner can…

Ability to create the resume token based on oplog item
CHoose an oplog event to set the resume token for, instead of needing to run the change stream for system to create a resume token
Why: Concerns about many stream re-reading a full oplog if failure before finding first event

Cloning User/Roles along with Database
When cloning a Database it would be helpful if User/Roles could be cloned directly as well and carried over.

Pass document field to $loolup.from and $lookup.as
Suppose I have collection of documents { entityId, entity }, where entity is names of other collections I would like to make aggregation with lookup and be able to pass entity value to $lookup from and as
db.collection.aggregation([{ $lookup: { from: '$entity', let: { entityId: '$entityId' }, pipeline: [{ $match: { $expr: { $eq: ['$_id', '$$entityId'] } } }], as: '$entity' } }])
As of mongo v4.4.4 that seems not working.

Have a role that allows that user to control the schema of a collection
As a DBA or Data Architect, I want to be able to enforce data governance policies like schema control. Users of MongoDB cannot change the schema however DBA or named individuals have the ability to change the schema.

2dindex
geoIntersect queries on spherical geometries are not adapted to our use case. Our need is to retrieve a list of tiles intersecting a given area of interest (AOI) in a flat 2d geometry.
Classical geo-spatial databases (PostGIS and Oracle Spatial) support this kind of approach at no extra cost and we would expect the same from MongoDB.
In MongoDB , using a 2dsphere index forces us to implement a workaround adding an artificial margin to the AOI and making a post-processing to remove false positives. See attached slides for explanations.

Diacritic insensitive contains search on a single field
I would like to perform a "contains" query on a single text field in a case insensitive and diacritic insensitive way. I would like the query to have the performance of the field being in a text index by itself (assuming that this gives the maximum speed).
It is usually the case that the text index already exists for multiple fields. This means that a text search then has to be combined with a complicated (to make it diacritic insensitive) regex expression to find the correct results.

Add an option for $addToSet to use a specific field in the array for uniqueness
Currently, the $addToSet for upserting to an array checks for object equality (when the array elements are objects). We sometimes need to check for uniqueness based on a specific field of the object rather than the object as a whole, and the only way to do this is to force single-threaded operation and to use $pull and $push.
If there is a way to specify the field to check uniqueness for the $addToSet , we would be able to perform writes normally.

Extended JSON
Add support for Extended JSON (EJSON. For example, {$date: "2021-01-01T00:00:00.000Z"} ) such that we do not have to resort to using the ISODate helper function in the MongoDB Shell and in Compass.

Arrow function support
Is there any plan to implement arrow functions support?
The current way to use functions (BSON type 13) is using traditional javascript functions:function() {
...
emit(key, value);
}
It would be great to support also arrow functions:
() => {
...
emit(key, value);
}

4.4 to the EU on regular instance for development!
I work on mongodb in the EU.. i want to use the atlas search but i also need some features of v4.4
In development and for general everyday projects where our clients don't have large user bases we generally go for M2 instances.. affordable while offering full text search.
The release of 4.4 is almost half a year old.. when will we see 4.4 released to the EU of regular M2 instances??

Bundle rest service together DB
As per current industry practice, REST/Json became standard way to deal with the data between the FE application and Backend DB. So if REST the server/service is bundled with DB it would eliminate the need of a middleware tier in most cases.
It means we can directly fetch data from a frontend application using REST/Json from mongoDB without requiring a thirdparty service.

Conditional TTL index
In case of auto purging sometimes user might want to ensure data has been archived before purging. If conditional TTL was allowed user could set value of a field to indicate document has been archived and then db can purge accordingly.
